LC29H Positioning Module

The lc29h positioning module simultaneously receives and processes signals from all constellations (gps, glonass, beidou, galileo, and qzss), maximizing satellite signal accessibility in conjunction with sbas support. this module supports the reception of dual-band l1 and l5 signals, thereby ensuring that terminals can accelerate convergence time, improve positioning accuracy, and achieve rapid response times even when the signal is interrupted. the dual-band design significantly reduces the multipath effect experienced near tall buildings or in deep urban valleys, providing reliable positioning performance. additionally, some versions come equipped with 6-axis imu sensors (3-axis accelerometer + 3-axis gyroscope) and integrate rtk and dr positioning algorithms, enabling accurate positioning at the level of continuous line scenarios where satellite signals are partially or completely blocked, such as in underground parking lots, tunnels, urban valleys, or forests. once the satellite signal is regained, the lc29h combines sensor data with gnss signals, and integrated navigation can provide rapid convergence times and centimeter-level positioning accuracy. to enhance performance when used with passive antennas, the lc29h features an internal lna and an internal saw filter, ensuring high sensitivity and excellent positioning accuracy.
